Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of human health monitoring, and in particular to a human health status monitoring system and method based on an electronic nose. Background Art
[0002] Electric toothbrushes are increasingly popular among consumers due to their ease of use and improved oral hygiene. As people's expectations for quality of life continue to rise, more and more smart wearable devices are being used to monitor vital signs. However, current smart wearable devices primarily monitor daily physical signs, such as pulse, respiration, and blood pressure.
[0003] Currently, there is no routine monitoring of chemical signs inside the human body. This invention uses a smart toothbrush with an integrated electronic nose chip to analyze gases produced by the oral cavity and the digestive and respiratory tracts connected to the oral cavity, thereby achieving early screening, diagnosis and condition monitoring of human diseases.
[0004] Traditional gas sensors are typically single metal oxide semiconductor (MOS) sensors, which detect specific odors by exploiting the change in resistivity (or conductivity) of specific semiconductor materials in specific gas environments. These sensors cannot distinguish between multiple odor components and have low sensitivity for complex odors. They also have poor gas selectivity and are easily affected by complex gas states, temperature, and humidity fluctuations. They require a long time to achieve stable detection and have a slow response. They also collect little information and rely on trigger-based detection, making it impossible to extract odor signature information or perform qualitative and quantitative gas analysis by comparing it with a known gas database.
[0005] At present, electronic nose technology has not been widely used in the field of human health monitoring, especially the lack of a convenient and practical human health monitoring device and method based on electronic nose. Summary of the Invention

[0013] Preferably, the user interaction module includes a mobile terminal APP and an LED indicator light provided on the smart toothbrush; The mobile terminal APP displays the health analysis report; The LED indicator light indicates the health status level through different colors.
[0014] Another aspect of the present invention discloses a method for monitoring human health status based on an electronic nose, comprising the following steps: S1: Place the smart toothbrush with an integrated electronic nose chip at a predetermined position in the oral cavity; S2: Start the electronic nose chip in non-brushing mode to collect oral gas data; S3: preprocessing and feature extraction of collected gas data; S4: Evaluate the extracted features based on the health status assessment model; S5: Generate a health status report based on the analysis results.
[0015] Preferably, said S1 includes positioning the toothbrush by biting the teeth.
[0016] Preferably, the data collection time of the electronic nose chip in the non-brushing mode in S2 is 30-60 seconds.
[0017] The advantages of this invention over existing technologies are: the electronic nose chip is integrated into the smart toothbrush, allowing users to collect oral gas data during daily brushing without the need for additional operations or equipment, enabling convenient monitoring of human health status, and timely feedback of health assessment results to users, enabling users to promptly understand their health status and take appropriate measures; In the present invention, users can view detailed health analysis reports through their mobile phones, and can also quickly understand their own health status through the color of the LED indicator light during brushing.
